What is difference between Global n Local Macro Variables..?

Answer

Two types of scopes exist for macro variables: global and
local. Global macro variables exist for the duration of the
SAS session and can be referenced anywhere in the program--
either inside or outside a macro. Local macro variables
exist only during the execution of the macro in which the
variables are created and have no meaning outside the
defining macro.
